Comment 2 for bug 2043425

Bringing the side conversation here:

- the Pro Client has https://canonical-ubuntu-pro-client.readthedocs-hosted.com/en/latest/references/api.html#u-pro-packages-updates-v1 , which shows the same updates in security status but versioned and machine consumable (security status --format json will be deprecated at some point in time, when we are sure the APIs are sufficient)

- There is not currently a way of getting the changelogs for the ESM versions, and if there is and I don't know about it, not when you are unattached. So the good way to go would be replacing the changelog entry with this explanation about how Pro works a little different. If you want to include technical details from our side in this explanation I'm glad to help.
